To complicate the matter, my TSD instructor was the brother of the federation head, so he didn't even pretend to follow the official curriculum. He had also cross trained in karate, kung fu, and judo. So I have NO idea what he taught me.
The steps I can remember are an ultra deep front stance. I think it has a name in Kung Fu but I can't remember so let's just call it a very deep front stance. You step forward with those long straight arm windmill attacks that are from that style that never bends their arms. I know I'm being specific here.

First step is a back fist in the front and a low sideways hammerfist in the back, then you step again and it's two windmilling overhead hammerfists. That's all I remember.
Anyone have any idea what I'm looking for? I thought it might be Sip Soo, but the youtube videos of that form look stupid and are not what I remember.
